We study a collection of self-propelled polar particles on a two-dimensional substrate with
birth and death. We introduce a minimal lattice model for the system using active Ising spins …

The Green's function plays an important role in many areas of physical sciences and is a
prime tool for solving diverse hydrodynamic equations in the linear regime. In the present …

Geometric confinements are frequently encountered in the biological world and strongly
affect the stability, topology, and transport properties of active suspensions in viscous flow …

Breaking spatial symmetry is an essential requirement for phoretic active particles to swim at
low Reynolds number. This fundamental prerequisite for swimming at the micro scale is …

Finding the fastest path to a desired destination is a vitally important task for microorganisms
moving in a fluid flow. We study this problem by building an analytical formalism for …

Geometric confinements play an important role in many physical and biological processes
and significantly affect the rheology and behavior of colloidal suspensions at low Reynolds …

The migration of microorganisms or synthetic microscale robots is always affected by the
local environment, such as the surrounding fluid or muscular contractions. This paper …

A deep understanding of the physical interactions between nanoparticles and target cell
membranes is important in designing efficient nanocarrier systems for drug delivery …

A Marangoni surfer is an object embedded in a gas–liquid interface, propelled by gradients
in surface tension. We derive an analytical theorem for the lower bound on the viscous …

We investigate theoretically, on the basis of the steady Stokes equations for a viscous
incompressible fluid, the flow induced by a stokeslet located on the centre axis of two …
